For the first time, researchers from the German Aerospace Center have depicted Mount Everest, the 'Roof of the World', in 3D using optical satellite data at a maximum resolution of just half a metre. These 3D images are the outcome of a collaborative venture between the DLR Institute of Robotics and Mechatronics, the German company 3D RealityMaps GmbH and DigitalGlobe, one of the world’s leading providers of commercial, high-resolution Earth observation products. A video allows the viewer to follow the route taken by 15 mountaineers on a current expedition to the summit of the world’s highest mountain.
